Use this guide to resolve School Census Query 2502Q
Error 2502:
- DfE Validation:
- Autumn census:
Where <SessionsPossible> is equal to zero then either ‘X’, ‘Y’ or ‘D’ should be greater than zero - OR <SessionsExceptional>should be greater than zero
- Spring and Summer census:
Where <SessionsPossible> is equal to zero then either ‘X’, ‘Y1-7’, D or ‘Q’ should be greater than zero
- Explanation:
- A Student should only be recorded with zero sessions possible if they spent all of the period for which the attendance data is being collected at another school OR were not expected to be in school.
- Go to Reports>Attendance>Attendance Certificate and select the Students identified and then define the date ranges from (Modules>Census>School>Select Return>Attendance includes) click Preview
- Check that all the Attendance Codes recorded against the Student are correct for the dates selected.
- If a Student has zero sessions possible then Attendance Codes X (non compulsory school age absence), Y ( unable to attend due to exceptional circumstances) OR D ( dual registration) should be greater then zero OR Sessions Exceptional should be greater than zero. For further guidance on DfE Termly Attendance see here.
- To amend any attendance go to Modules>Attendance>Manage>Attendance>Student. See How to Manage Attendance
- If it’s correct for the Student to have zero sessions possible at your School, this is a return level note when submitting to Collect to explain.

You can use this report to review Attendance Codes and Possible Sessions Recorded
- On Report for move to Student and then click the Find button to choose the Student(s) this will open the Student Selector list for all Students that are currently on roll.

In this example we can see the Sessions Possible in the POS column and the Attendance Codes in the table.
- Note: in the example below ‘X Non-compulsory school age absence – not counted in possible attendances’ has been recorded for 2 weeks of the Students Attendance and this returns zero sessions possible in the Pos column.
